First, consider the voltage requirements of your light. If your 4W UL emergency led driver, use a 12-volt driver; if it uses 24 volts, use a 24-volt driver, etc. When choosing a driver for a constant-current LED, you must also consider the LED’s current output, which is measured in amps or milliamps. In short, make sure your driver will achieve power outputs within your light’s specified ranges: consider both voltage and current range for a constant-current driver, and simply voltage range for a constant-voltage driver.
